Abstract:
A light source assembly includes a heat interception portion disposed between a light source unit and an optical member. The heat interception portion may be extended from the light source unit. Alternatively, the heat interception portion may be extended from a receiving container that receives the light source unit and the optical member. The heat transferred from the light source unit to the optical member may be reduced. Thus, deformation of the optical member may be prevented and the display quality of the image from the liquid crystal display apparatus using the light source assembly may be improved.
Abstract:
An illuminated shelf includes a tempered transparent glass panel having edges each housed in a slot of a housing defining a chamber through which and/or in which light is generated to illuminate the transparent panel. Each housing is preferably snap-secured together to access the chamber interior for purposes of replacement and/or repair. Each housing can be totally or partially encapsulated and the encapsulation includes conductors which are operative in any position of vertical adjustment or sliding adjustment of the shelf.
Abstract:
A backlight system (10) includes a light source (30) having a light emitting portion (31) and a wire (32); and a bracket (20) having a plurality of fastener (24) which holds the light emitting portion thereby mounting the light source on the bracket, the wire are electrically connected with the bracket. The backlight system can stably fix the light sources in the bracket, and it is convenient and safe to exchange the light sources.
Abstract:
A linear light source having an indented reflecting plane comprises a light guide bar and a light source component. The light guide bar is a polygonal cylinder having an arc-shaped plane. Any two opposed surfaces of the cylinder are an indented reflecting plane and an arc-shaped emission place, respectively. The other surfaces are composed of a plurality of reflecting layers. Through controlling the light-emission slope and height of the indented reflecting plane, the light will be more uniform. The brightness can also be enhanced through the light collecting effect of the arc-shaped emission plane. Moreover, the light source component can let the light emission angle of each LED be closer to accomplish a shorter useless region through the arrangement of the LEDs.
Abstract:
A structure of an illumination apparatus is described. The structure has a light guide rod arranged at one lateral side of a light guide plate, and plural light sources located below the light guide rod. The light guide rod has at least one tilt plane formed thereon in order to guide the light emitted from the light sources to the light guide plate such that uniform planar light could be generated therefrom. A plurality of notches is formed in the tilt plane, and a plurality of depressed or protruding dispersion dots is formed on an out-going plane of the light guide rod. The structure further includes an anti-reflection layer positioned between the light guide rod and the light guide plate.
Abstract:
A back light unit (BLU) disposed under a display panel has a light guide plate (LGP), and a light source generator for generating a light source disposed on a first side of the LGP. The LGP has a first reflecting film, which is coated on a bottom surface of the LGP, for reflecting the light source generated by the light source generator, and is utilized for scattering the reflected light source to the display panel through a top surface of the LGP.
Abstract:
A light guide plate (32) in accordance with the present invention includes a base (23), and an intervening layer (22) formed on the base. The intervening layer includes a light emitting surface (24) defining a plurality of V-shaped grooves (241) thereat. An index of refraction of the intervening layer is less than an index of refraction of the base.
Abstract:
A vehicle light can include a light source, a major reflecting surface, a projection lens, and a shutter. A first reflecting surface of an ellipse group reflecting surface preferably has a first focus on the light source and a second focus, capable of being inserted in or removed from an optical path from the light source to a second fixed reflecting surface. A first fixed reflecting surface of a parabolic group reflecting surface can include a focus on the second focus of the first reflecting surface, and at least two second reflecting surface elements. The second fixed reflecting surface can include a first focus on the light source and at least two third reflecting surface elements for reflecting light rays that have traveled an optical path from the light source thereto without being reflected by the first reflecting surface.
Abstract:
The light source mechanism of a scanner provided in the present invention is to provide a plurality of light-emitting diodes that are placed uniformly beside a light-guide panel. The light emitted from the light-emitting diodes further passes through the light-guide panel, and is incident onto the scanning platform. Since the light-emitting diodes are uniformly placed beside the scanning platform, the brightness of the light incident onto the scanning platform is more uniform than that of the prior art using a line type light source such as a CCFL (Cold Cathode Fluorescent Lamp) of a scanner, hence the light source mechanism provided in the present invention achieves a better image scanning with a remaining cost of a scanner
Abstract:
The present invention discloses a panel branch to be associated with an artificial tree. The panel branch includes a plurality of twigs, a channel element, an number of inserts, and a hook-like member. Each twig is inserted through an aperture in the insert and the insert, in turn, is placed in and secured in the channel element. The hook-like member has a short side and a long side. The long side of the hook-like member is secured in the channel element and the short side is used to secure the panel branch to an artificial trunk. In addition, optical fibres are associated with the twigs of the panel branch. Each optical fiber is threaded through one of the apertures in an insert and gathered into a bundle. When the panel branch is associated with the artificial tree, a socket with a light source is provided to receive the bundle of optical fibres such that the branch is lighted.
